The Measurement and Offline Interface (MOI) is a measurement and analysis interface that was created as a tool to help with mobile or repeated testing and analysis. This video tip covers the setup of a Measurement, Online Measurement and Analysis, and Offline Analysis. The topics covered are: Measurement and Analysis Setup Creating settings modifications that […]

The conversion of an analog input signal to digital data is performed by an Analog to Digital Converter (ADC). Typically, an ADC is not able to convert any input voltage level, and is in fact limited to a maximum voltage (usually 1.2V for example). However, depending on the specifications, transducers don’t necessarily have a matching […]

PAK – MKII Hardware Grounding and Electrical Noise Tutorial A topic that comes up frequently at PAK support is electrical noise in measurements caused by improper sensor application or grounding techniques. This video attempts to explain the basics of hardware grounding and sensor application to prevent electrical noise. It also covers some rules of thumb […]

June PAK Video Tip: PassBy Software Tutorial The June PAK Video Tip has been posted! This month’s video tip covers the Software Setup of the PAK PassBy Assistant. The PAK PassBy Assistant helps you setup and run PassBy testing for a variety of regulations and standards. In this video tip we demonstrate step by […]

A way to minimize the effect of aliasing is filtering the analog signal by means of a low-pass filter (see PAK Academy: Anti-Aliasing Filters). Such an analog filter is built out of electrical components, such as resistors and capacitors. In order to attenuate the frequency range above the Nyquist frequency sufficient enough, the slope after […]

Aliasing is an effect which occurs when sampling an analog signal. It is important to recognize that there is no way to prevent this effect from happening. The only thing we can do is to minimize its effect. A common misunderstanding is that aliasing can be prevented using a “high enough” sampling rate, making sure […]

Sensor Calibration in PAK In this short tutorial we cover how to calibrate your acceleration, sound, and slow – two point calibration channels (like a string potentiometer or temperature sensor). We cover two methods for entering or measuring calibration values as well as investigating some settings and features to make your calibrations more customized and […]

Interactive Graphic Parameters and Data Viewing Tools In this tutorial we demonstrate some tools in PAK that allow you to quickly analyze your measurement data. This interactive method gives you the flexibility to change your plots and analyses on the fly. You get access to all of PAK’s streaming analysis capabilities (like FFT, Orders, PsychoAcoustics and more). You also […]
